The present: invention therafore provides a proce~P of

~teps o~ heating an oqueous reaction medium to a temperature in the
range o~ from about 170F ~C) to about 225F ~10~C);

Leonardite ore~ have long been known to be ~our~e~ of
organic materials adapted for u~e a~ ~oil an~ ~oliar additives
having application in the regulatlon of plant yrowth. In
particular, leonardite or~ i~ recognized as a primary ~ource ~or a
wide variety of humates and humic acids. A wide variety o~
processe~ have been proposed for the extraction of the humic
fraction~ from leonardite ore for use o~ the compositions ~o
extracted in treating plants to modify plant vegetative ~rowth and
fruiting and the uptake of nutrie~ts by plant~ 80 treated.
lZ~7l~

Leonardite ore is ~elieved to be an oxidized
form of lignite ore, which is, in e~fect, a precursor
to leonardite ore in the biochemical and chemical
pathways o~ natural leonar~ite synthesis. Hence, it
is recognized that any mined sample o~ leonardite ore-
bearing earth is expected to contain at least some
lignite ore, as well as a plurality of or~anic an~ in-
or~anic impurities. Accordin~ly, as used herethrou~h-
out, the term "leonardite ore" will he understood as
re~errin~ to ore samples inclusive of lignite as well.
Fu~-~he~e~ it is understood that many known pro-
cesses for extracting humic acids and humates from
leonardite ore~ actually result in the extraction of
fulvic and phenol carboxylic fractions as well. It is,
accordinqly, to be recoqnized that the term "humic
acid", as used herein, is not intended to he construed
as excluding the possibility of the nresence of fulvlc
acids and phenol carboxylic acids in fractions and
compositions extracted and produce~ by known ~rocesses
or the processes disclosed herein.
WhiIe many of the humic acid nroduc~s prenared
usin~ known~techniques of extraction From leonardite
ore have been e~fective to one dearee or another in
stimulatin~ plant growth when applied thereto, the~
response of various plants to the ap~lication thereon
of such compositions has proven to be~inconsistent.
Further, some known processes for extractin~ humic acid
products and compositions for leonardite ore result in
the nroduction of compositions havinq limited stability
:
:
~267~387
against degradation and consequently havinq limited
shelf lives whereby storage thereof for protract periods
prior to a~plication to plants and soil results in a
significant diminishment of the eff~ectiveness of the
composition.
Moreover, ~ew such comp~sitions Prepared by
known processes have been known to effectively increase
both vegetative ~rowth and fruiting in a variety of
plants and mos~ of such beneficial effects obtained hy
applying compositions prepared conventionallv have been
inconsistent and ephemeral.
Therefore, it has long been known that it would
lS be desirable to have a process for extractina humic
acids from leonardite ore which would result in the
nreparation of a produ~t or composition which is capahle
of bein~ stored for ~rotracted periods oE time without
substantial de~radation thereof or diminishment of the
effectiveness thereof for use in stimulatinq and requ-
lating plant growth. Further, it has been reco~nized
that there is a need in agriculture for such products
and preparations, the use of which is caPable of in-
creasing both the vegetative qrowth of ~lants on~which
it is applied, as well as the fruiting thereof. More-
; over, it has~been known that it woul~ be desirable Lo
have such~a product and a method~ for the use thereo~
which finds applicatlon in~modify~ing the veqetative
growth and fruiting of a wide variety of crops with
substantial~ly conslstent ~and repeatable results in awide varie;ty of ecological condition.
'
: '
~2~ 37
Therefore, an improved ~rocess for extractin~
humic acids from leonardite ore is desired.
The preferred processes disclosed herein are
S capable of reliably and consistently producin~ compo-
sitions~havin~ high stability a~ainst de~radation and
which are capable of bein~ stored for pro~racted
periods of time without de~radation thereof. The
plant growth regulator and a method~for;the use thereof
disclosed herein~ can be employed dependably and in~a
, :
manner fully compatible with other a~ricultural and
manu~acturin~ Practices and are well suited for use on
a wide~variety of annual and perennial~plants a~nd are
particularly well suited for use on CottoQ, ~rape,
olive and tomato plants. The preferred plant qrowth
modifier and~ ~ethod disclosed here~in can be employed
in conjunction with conventional fertilizers, ~row~th
regulators~, an~d~ equipmen;t for the spplication thereof
without diminiahment of~the bene~icial eEfect of either
the plant~ ~rowth modifier and method of the ~resent
invention, or that of the conventinal~ plant ~rowth
regulators, fertilizers, or methods.
These and o~ther features and advanta~es will

- I. PROCESS FOR PREPARING PLANT GROWTH STI~'IULATING
COMPOSITIONS AND PRODUCTS PREPARED THEREBY.
The process disclosed herein is adapted for llse
in the extraction of a variety of humic acids and humic
acid derivatives by the~reaction of organic chelatinq
agents with leonardite ore. Preferably, leonardite ore
having a relatively high humic acid content, such as
~that commonly~mined in~North: Dakota ha~vlng humic acid ~ :
~: contents as h:igh as 80~ by weight,:is use~ in prac:tic-
: ing the ~process of the present invcntlon. Howavar,
inasmuch as the process herein described is believed
~to: extract -a fairly specific spectrum or fraction of
humic acids out o~ the overall number of humic acids
: present in the leonardi~te ore, comprisina perhaps as
~: : little as 8 to 10% by weiaht of the total humic acid
~: : content of the ore, it will be recognized that the
percentaae~ by ~wei~ht of~ humic~ acids i~n a ~iven:ore
sample, ~and the origi~n of the ore samplet are not to be ~:
considered controllin~ or limitin~ in the practice o~f
: : : the described process~
Leonardite ore, ~referahly crushed prior to
use thereof, is reacted in an a~ueous:med:ium in the:

ammonium gluconate; ammonium glucoheptonate; ammonium

agents serve as reactants and, possibly, as ~eans for
limiting the potentially deleterious effects of the
presence of otherwise~free metal ions in the resultinq
composition. Preferably, :the pH of the resultant
aqueous composition of extracted humic acid derivatives
is then adjusted to stabilize the composition a~ainst
lS degradation and to provide a prolon~ed potential shelf
life. In a modified form of the process of the present
invention, the composition derived by the reaction of
leonardite ore with organic chelatin~ agents is blended
with a humic acid composition prepared hy the reaction
of leonardite ore with potassium hydroxide or sodium
hydroxide. In a further modification of the subject
~rocess, the compositlon is enhanced as to nutritive
value by the introduction of nitrogen, phosphorous,
potassium and other nutrients~
~hile the exact make~up of the compositions of
the present invention produced by the processes hereof
are unknown. and have resisted analysis, they:are known
to produce a simulated hormonal efect, or to stimulate
- a hormonal response, in plants to which they are
applied. ~ :
~L;26~7~8~
In order to disclose the process still more
clearly, attention is invited to the following illu5-
trative examples. It is understood, however, that
these examples are merely illustrative and that the
subject invention is not to he limited to the specific
conditions or details set forth. In the following
examples, all parts are by wei~ht, unless other~ise
indicated.
EXAMPLE I
9 parts (by wei~ht) of leonardite ore is intro-
duced into 75 parts of water previously heated, prefer-
ably, to a temPerature in a range of about 170F (77Cj
to 190F, (88C), but not exceedinq 22~F (107~). 15
total ~arts by wei~ht of sodiu~ gluconate is then added
and the resultant mixture is mixed for 5 hours to per-
mit complete reaction. ~fter mixing, the mixture is
pumped to a settling tank for 24 hours to 7 days to
separate into liquid and 501id phases, after which the
supernatant, partially separate liquid phase, contain~
ing the subject composition, is pumped to standard
cone tanks ~or 3 to 7 days ~or fu~ther settlinq~ The
settled liquid composition is pumped to a mixer and
adjusted therein to pH of 12.5 or higher by the addi-
tion o ~concentrated sodium hydroxide; or potassium
hydroxide. The ~ resultant a~ueous comPosition i5 then
adapted to be stored for periods of at l~east one year
prior to use thereof without signiicant deqraAation
or loss of e~fectiveness. ~ptionally, the composition
can he used at extracted pH ranqe which can vary ~row
4.5 to 6.5l depending~upon the dielating agent used.

EXAMPLE II
The process described in Example I is repeated
and the resultant composition, hereinafter designated
as "Composition A", is mixed with a liquid composi-
tion, hereinafter designated as "Composition B",
produced by the process described immediately below.
In preparing Composition B, about 72 to 74
parts (by weight) of water is heated to at least 180F
(82C). Preferably, the water temperature is about
200F (33Cj. About 20 to 22 parts oE leonardite ore
is added to the water and bIended for about 1/2 hour.
5 parts o~ potassium hydroxide or sodium hydroxide is
added to the water to raise the pM to about 11.00, and
mixed for a period o about 2 to 5 hours. Thereafter,
one part of hydrogen ~eroxide is added. The liquid
composition is permitted to settle, and excess solid
; ~ matter IS r emoved.
About S0 parts Oe Composition ~ are added to
about 12.5 parts of Com~osition A in about 37.5 parts
of water. The resultant mixture is mixed or blended
for a period sufficient to produce a substantially
homogeneous mixture. The ~H is adjusted to about 12.0
by the add~ition of sodium hydroxide or potassium
hydroxide. The mixture, herelnafter desiqnated as
"Composition C", is again blended to ensure homo~eneity.
:
12~7
It is believed that the presence of positive
ions and ammonia are detrimental to the effects of the
resultant composition on plant growth, and more parti-
cularly on plant fruitage, and therefore it is impor-
S tant that care be taken in preparation and use of the
composition produced by the process of this example to
avoid the introduction of ammonia or dissociable metal
salts into the mixture.
EXA~IPLE III
Ahout 14 parts of Composition A, 9 parts Com-
position B, 33.1 parts of phosphoric acid, 11.9 parts
potassium hydroxide, 6.2 parts ammonia, 18.3 ~arts of
water, 3.6 parts of zinc, 2.5 parts of iron, and 1.4
parts of manganese are mixed to produce a~composition,
hereinafter designated as "Composition D", having as
active ingredients humic acids, potassium phosphate,
ammonium phosphate anc~ the aforementioned minor nutri-
ents. The resultant composition is one having a
positive effect on the rate of vegetative growth and
fruiting o~ plants to which it is applied and~which
also provides essential nitrogen, ~hosphorous and
potassium nutrients, the need for which increases with
the accelerated growth. In particular, Composition D
provides relatively hiah levels of phosphates which are
essential to plants during ~ruiting.

II. rqET~OD FOR U5E OF PLANT GROWTH STI~ULATING
COMPOSITIONS
In accordance with the subject invention, plants
are treated with single or multiple applications of
an effective amount of the plant qrowth modi~yin~
compositions produced by the processes hereof diluted
as necessary for selected rates of a~plication thereof
In general, the compositions are most effective if
applied on annual crops prior to irrigation or prior
to or simultaneously with bloom initiation. On peren-
nial crops, the composi~t;.oQ~ are~ bs~t applied~immedi-
ately prior to or after harvest or,~during dormancy,
at least one month before the plant enters a vegetative
cycle. Soil or foliar aPpllcations are ef~ective. ~s
described previously, the~effect of the compositions
on the growth of plants to which they are applied is,
in many c~ases, hormonal or quasihormonal in nature.
: :
; ~ ~ The pro~ducts are compatible with~many fertili-
zers as well as ~rowth requlators which are a~apted to
restrict growth, such as the growth re~ulator commer-
20 cially available as a watersoluble comPosition under
the trademark "PLX", containin~ on a wei~ht ~asis
; 4.2% N,N-dimethyl~ piperidinium chloride (hereinafter
designated as "PIX") and 95.8~ inert ingredients.
The~compositions produce noticeabl~e and consis-
tent increases in vegetative and fruitin~ qrowth on a
wide variety of plants~ particularlY when applied at
a stress point in the crop cycle~and particularly at
such~ stress times as the harvest~period and those
:
`: ~ ; :
~2~7~3~3'7
relatin~ ~o the watering of the plants, althvu~h the
timin~ of applications relatin~ to water-stress
periods in the plants' growth cycle is not believed as
critical for perennial crops as for annual crops. ~ow-
ever, if the compositions are applied to plants which
are in a vegetative state, the results of such applica-
tion will be minimally effective or inconsistent.
In order to disclose the method of the subject
invention still more clearly, attention is invited to
the following ill~strative examples. It is understood,
or course, that these examples are merely illustrative
and that the invention is not to be limited to the
specific conditions or details set forth. In the
following examples, all parts are by weight unless
otherwise indicated.
EXAMPLE I
Effects of the composition designated as Com-
position ~ on cotton plants ~rowing in California were
experimentally determined and the results are summariz-
ed in Table 1 below. The cotton, which was of a variety
commercially d~nominated as "SJ2", was grown on 30-inch
beds in soil havîng a type characterized as "oxali~
silty clay" with pH in the ran~e of from 7.~ to 7.7 to
a depth of one foot.

- 13 -
~ The test was conducted in three trials denomi-
nated Trials, 1, 2 and 3, respectivelyr and the trials
were compared a~ainst a fourth trial deno.ninated Trial
4, which served as a control. The cotton fields in
S which the cotton was grown were divided into plots.

The plots in all trials were irri~ated on the
same dates, as follows:
First irri~ation - June 22.
Second irrigation - July 24.
Third irrigation - Au~ust 8.
In each trial, includin~ Trial 4, which was the
control~, the seeds were treated with a commercially-
available conventional fun~icide. In~ Trial 1, the
seeds were treated prior to planting with both a fun~i-
cide and Composition C, applied as by sprayin~. The
seeds in Trials 2 and 3 received fun~icide treatment
only.
It will be apparent upon a review of the ~ata
of Table 1, that the plants treated with ComPosition D
in Trials 1, 2 and 3 evidenced a suhstantial incr~ase
in crop yield over those plants qro~n without such
ap~lication in Trial 4.
EXA~PLE II
The effect of Co~position A on several dif-
ferent varieties of qrape was experimentally tested~
and the results are set forth in Table II below. 160
acres of éach variety were treated by the soil appli-
cation of~ComPosition A and the results of such treat-
ment were compared with the yield of 160 ~acres of the
same variety of grape, located in the same vineyard,
but left untreated, to serve as a control. The appli-
cation of ~Composition A in each case was in earlyFebruary, which is a dor~ant period in the ~rowth cycle
of the grapevines.

In Table II, the average yields of qra~es in
tons per acre for the five~year period preceding the
year in which the test was conducted is set forth for
both the treated and untreated acres. Each variety of
~rape receive~ a single application. The yield in tons
per acre of the treated acres of each variety was
greater than that o the controlled acreage of each
variety.
EXAMPLE III
160 acres of ~rapevines of each of the varieties
listed in Table III below were treated with Composition
C at the rate indicated. Again, each 160 acre tract of
~rapevines treated was compared with 160 acres of un-
treated grapevines in the same vineyard and of the same
variety, left untreated to serve as a control. The
vines of the treated acreage received a single appli-
cation of Composition C in early February durinq the~
dormant period in the vegetative cycle o~ the vines.

As did the application of Composition A, set
forth in Table II in Example II, the applications of
Composition ~, the results of which are set forth
immediately above in Table III, provided a ~reater crop
yield per acre than was obtained from the untreated
acreage. It was also experimentally observed that the
vines of the treated acreage had a much more rapid and
voluminous vegetative growth and an earlier date of
maturity.
EXAMPLE IV
Olives of the Ascolino and Manzanillo varieties
were treated with Composition D and the results o~ such
treatment are set ~orth in Table IV~ The applications
of Composition D were made bv foliar s~rayinq.
~ oth the Manzanillo and, to a lesser extent, the
Ascolino varieties of olive, are cvclical or alternate
in their seasonal bearing oe olives. That is, normally,
in one of each pair of succee~i~ng years of growing
seasons, the trees of each variety will produce at a
depressed level relative to the other o~ suc~ succeeding
pair of~years. The trees of the control group of each
variety produced significantlv lower yields of olives
in the year in which the test was conducted as compared
to the preceeding;year, during which none of the trees
were treated. The trees each received a~sin~le appli-
catIon.

Each trial was replicated four' times and the
yield of seed cotton per acre for each trial represents
the averaqe of the yields o the four replications.
The cotton plants treated with the combina-
tion of PIX and Composition D were approximately six
inches taller, on the average, than the plants treated
solely with PIX. No delay in maturity o~ the cotton
was observed.
EXAMPLE VI
Varying rates of application o~ PIX and PIX
plus Composition D were tested against control plots
of cotton to determine the relative e~ects on the
yields of cotton plants so treated. The results are
summar1zed~in Table VI below.

Each trial was replicated four times and the
yield of seed cotton per acre for each trial represents
~he average yield of the four replications.
~gain, the growth pattern of the plants treated
with Composition D in combination with PIX showed an
avera~e increase in height of approximately six inches,
again with no delay in the maturity of the cotton. The
yields obtained from the application of Composition D
in combination with PIX resulted in si~nificantly
larger yields than those using PIX alone. However, it
is noted that the yields of the control group were also
significantly higher than the groups on which PIX
alone was applied.
Thus, it is seen that a ~rocess for ~roducing a
~lant growth modifyin~ composition, and a method or
the use thereo, useful in modiyin~ both veqetative
and fruiting growth in annual and perennial plants and
compatihle with conventional a~riculture methods,
materials, and practices, have been disclosed herein.
While the composition and method~ disclosed
herein are described in terms of particular ingredients,
and ranges thereof, to be used, it is obvious that
modifications and variations in~the nature and propor-
tions of the ingredients may be made without departing
from the~ spirit and scope of the invention, which is
not to he llmited o the illustratl-e dotails disclosed.
